摘要

尼日利亚每年都有丰富的降水,滋养着它的森林和农业,它有一个广泛的河流排水系统,它拥有宝贵的矿藏,刺激着商业和手工采矿活动。这些特点的结合使尼日利亚生产足够数量的健康食品以支持其人口的努力复杂化。有毒的重金属,如铅、镉和汞,以及有毒的类金属,如砷,也存在于其矿藏中,并通过自然途径逐渐迁移到尼日利亚的土壤和水中。然而,采矿活动可以释放出更高水平的有毒金属,这对尼日利亚的生态系统及其食物链产生不利影响。因此,人为活动造成的环境污染是尼日利亚一个主要的公共卫生问题。本文综述了尼日利亚和非洲本土野生和栽培植物以及牲畜和野生动物作为前哨物种对评价重金属作为环境压力源的重要性,以及在食品安全监测和预测对人类健康的潜在风险方面使用前哨物种的重要性。

Sentinel species for biomonitoring and biosurveillance of environmental heavy metals in Nigeria.

Nigeria receives copious annual precipitation to nourish its forests and agriculture, it has an extensive river drainage system, and it possesses valuable mineral deposits that stimulate both commercial and artisan mining activities. The combination of these features complicates Nigeria's efforts to produce adequate amounts of healthy foods to support its population. Toxic heavy metals like lead, cadmium, and mercury, and toxic metalloids such as arsenic, are also present in its mineral deposits and they migrate gradually into the soil and water of Nigeria by natural means. However, mining activities can liberate higher levels of toxic metals, which adversely affect Nigerian ecosystems and its food chains. Thus, environmental pollution due to anthropogenic activities is a major public health concern in Nigeria. This review covers the importance of native Nigerian and African wild and cultivated plants along with livestock and wild animals as sentinel species to evaluate heavy metals as environmental stressors and the use of sentinel species for food safety monitoring and for predicting potential risks to human health.
